IPC: A61M5/00
Filed: 1990-01-31
Abstract: PURPOSE:To bond a driving piezoelectric element on a diaphragm uniformly and easily in a micropump formed of a base plate, a diaphragm, and the like by providing the diaphragm center part with a supporting part with the tip thereof in contact with the base plate. CONSTITUTION:A diaphragm 6 is supported not only at its peripheral part by the engagement with a surface plate 3 but also at its center part by a protrusion 81. Accordingly, at the time of bonding a driving piezoelectric element 7 on the diaphragm 6, because of the protrusion 81 becoming a support and a stopper to oppose the pressing force to the piezoelectric element 7, the surface of the diaphragm 6 is hardly curved, and its flatness is maintained. The piezoelectric element 7 can be therefore bonded uniformly and stably, and even if the piezoelectric element 7 is pressed rather hard at the time of bonding, there is no fear of damaging peripheral joints, thus facilitating bonding work.

Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To execute a processing at high speed by constituting a digital signature generation processing based on an ellipse curve through the use of a method for effectively using an excess multiplication operation. SOLUTION: An excess operation after the generation of random numbers required for an ellipse curve ciphering processing and an excess operation in a signature generation processing are operated by using an excess multiplier 107. For effectively using the excess multiplier 107 even in an operation on an ellipse curve, a point on the ellipse curve is converted from a two-dimensional affine coordinate system into a three-dimensional coordinate system. Thus, an excess division operation in an addition operation on the ellipse curve is converted into an excess multiplication operation and the excess multiplier 107 can be used in the excess multiplication operation.  In such a case, ABR<-1> modN, A<2> R<-1> modN and AR<-1> modN, which show a calculation object numeric value generated in an intermediate operation processing, are calculated by the multiplication operation of excess multiple length against positive integers A, B, N and R (A and B are input variables or intermediate variables, N is an input variable and R is a numeric value given as a constant).

Title: Metal refining agent
Inventor: HIROKAWA NORIO
IPC: C21C7/04
Filed: 1982-02-12
Abstract: PURPOSE:To prevent the evaporation of Ca in molten steel and to increase the deoxidizing and desulfurizing effects by using a Ca-Al alloy, CaO and Al2O3 as principal components in a prescribed ratio and uniting CaF2 with them. CONSTITUTION:This metal refining agent consists of 20-50% Ca-Al alloy and 80-50% CaO+Al2O3 as principal components and of 0-30% CaF2. When the refining agent is added to molten steel, the sudden contact of the alloy phase with the molten steel is prevented, and the melting proceeds slowly. As a result, the evaporation of Ca is reduced, and the deoxidizing and desulfurizing effects on the molten metal are increased.
